SPOILER!!!!!!! If you put the gravity bomb up in the V shape under the generator the lobbers shot (purple one) will bounce of the gravity bomb and hit the generator.

Sorry for asking this, but how do I get to the point of destroying the generator? I see the whole pinball setup, and I see the generator, but I can't figure out how to interact with any of it, since it's behind the invisible wall and red shields respectively.

Oh, silly me. Didn't realize there's an invisible wall there. Thanks.

Spoilers!!!!!!!!!!!!!!!!!!!!!!! go inside the level trough the top to get to the goal.

Cool level. But...what is supposed to happen after the generator is destroyed? No idea what to do next.
